<Extension()>
Public Function HasValueGenerationStrategy (propertyBuilder As IConventionPropertyBuilder, valueGenerationStrategy As Nullable(Of SqlServerValueGenerationStrategy), Optional fromDataAnnotation As Boolean = false) As IConventionPropertyBuilder

參數

propertyBuilder
IConventionPropertyBuilder

要設定之屬性的產生器。

valueGenerationStrategy
Nullable<SqlServerValueGenerationStrategy>

價值產生策略。

fromDataAnnotation
Boolean

指出是否已使用資料批註指定組態。
